Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP- based internets. In particular, it defines extensions to the Remote Network Monitoring MIB for managing 802.5 Token Ring Waldbusser Expires March 5, 2001 [Page 1] Internet Draft Token Ring Extensions to RMON September 5, 2000 networks. The Remote Network Monitoring MIB, RFC2819, defines a framework for remote monitoring functions implemented on a network probe. That MIB defines objects broken down into nine functional groups. Some of those functional groups, the statistics and the history groups, have a view of the data- link layer that is specific to the media type and require specific objects to be defined for each media type. RFC2819 defined those specific objects necessary for Ethernet. This companion memo defines those specific objects necessary for Token Ring LANs. In addition, this memo defines some additional monitoring functions specifically for Token Ring. These are defined in the Ring Station Group, the Ring Station Order Group, the Ring Station Configuration Group, and the Source Routing Statistics Group. 1. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [1]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in STD 58, RFC 2578 [5], RFC 2579 [6] and RFC 2580 [7]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in STD 15, RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574 [12]. Waldbusser Expires March 5, 2001 [Page 2] Internet Draft Token Ring Extensions to RMON September 5, 2000 o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13]. o A set of fundamental applications described in RFC 2573 [14] and the view-based access control mechanism described in RFC 2575 [15]. A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [18]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB.

Guidelines for implementing RFC2819 objects on a Token Ring network Wherever a MacAddress is to be used in this MIB the source routing bit is stripped off. The resulting address will be consistently valid for all packets sent by a particular node. 2.1. Host Group Only Token Ring isolating errors will increment the error counter for a particular hostEntry. The isolating errors are: LineErrors, BurstErrors, ACErrors, InternalErrors, and AbortErrors. ACErrors will increment the error counter only for the nearest upstream neighbor of the station reporting the error. LineErrors and BurstErrors will increment the error counters for the station reporting the error and its nearest upstream neighbor. InternalErrors and AbortErrors will increment the error counter for the station reporting the error only. In addition to these isolating errors, congestionErrors will be incremented in the host entry of the station that reports the errors in an error report frame. The hostOutPkts and hostOutOctets counters shall not be incremented for packets with errors because the monitor cannot receive all error packets with which to update these statistics. 2.2. Matrix Group Error counters are never incremented because the monitor cannot recieve all error packets with which to update these counters. 2.3. Filter Group The following conditions make up the status bitmask for token ring networks: bit # Status 3 First packet after some packets were dropped 4 Packet with the Frame Copied Bit set 5 Packet with the Address Recognized Bit set Waldbusser Expires March 5, 2001 [Page 4] Internet Draft Token Ring Extensions to RMON September 5, 2000 For the purpose of the packet match algorithm, the filters assume a 32 byte RIF field. Thus, when matching, the filter is compared to the packet starting at the AC byte of the packet, until the end of the RIF field; then the unused RIF bytes in the filter are skipped and matching proceeds from that point. Any filter "care" bits in the RIF that don't correspond to bytes in the input packet will cause the filter to fail. 2.4. Other comments Because soft error report packets may be sent with assured delivery, some errors may be accidently reported twice on devices that perform the RMON function promiscuously.

Overview of the RMON Token Ring Extensions MIB The Remote Network Monitoring MIB, RFC2819, defines a framework for remote monitoring functions implemented on a network probe. That MIB defines objects broken down into nine functional groups. Some of those functional groups, the statistics and the history groups, have a view of the data- link layer that is specific to the media type and require specific objects to be defined for each media type. RFC2819 defined those specific objects necessary for Ethernet. This MIB defines contains four groups that define those specific objects necessary for Token Ring LANs. In addition, this memo defines some additional monitoring functions specifically for Token Ring. These are defined in the Ring Station Group, the Ring Station Order Group, the Ring Station Configuration Group, and the Source Routing Statistics Group. 3.1. The Token Ring Statistics Groups The Token Ring statistics groups contain current utilization and error statistics. The statistics are broken down into two groups, the Token Ring Mac-Layer Statistics Group and the Token Ring Promiscuous Statistics Group. The Token Ring Mac- Layer Statistics Group collects information from Mac Layer, including error reports for the ring and ring utilization of the Mac Layer. The Token Ring Promiscuous Statistics Group collects utilization statistics from data packets collected promiscuously. 3.2. The Token Ring History Groups The Token Ring History Groups contain historical utilization and error statistics. The statistics are broken down into two groups, the Token Ring Mac-Layer History Group and the Token Ring Promiscuous History Group. The Token Ring Mac-Layer History Group collects information from Mac Layer, including error reports for the ring and ring utilization of the Mac Layer. The Token Ring Promiscuous History Group collects utilization statistics from data packets collected promiscuously. Waldbusser Expires March 5, 2001 [Page 6] Internet Draft Token Ring Extensions to RMON September 5, 2000 3.3. The Token Ring Ring Station Group The Token Ring Ring Station Group contains statistics and status information associated with each Token Ring station on the local ring. In addition, this group provides status information for each ring being monitored. 3.4. The Token Ring Ring Station Order Group The Token Ring Ring Station Order Group provides the order of the stations on monitored rings. 3.5. The Token Ring Ring Station Config Group The Token Ring Ring Station Config Group manages token ring stations through active means. Any station on a monitored ring may be removed or have configuration information downloaded from it. 3.6. The Token Ring Source Routing Group The Token Ring Source Routing Group contains utilization statistics derived from source routing information optionally present in token ring packets. 4. Terminology The 802.5 specification [20] defines the term "good frame" as a frame that is bounded by a valid SD and ED, is an integral number of octets in length, is composed of only 0 and 1 bits between the SD and the ED, has the FF bits of the GC field equal to 00 or 01, has a valid FCS, and has a minimum of 18 octets between the SD and the ED. This document will use the term "good frame" in the same manner. Waldbusser Expires March 5, 2001 [Page 7] Internet Draft Token Ring Extensions to RMON September 5, 2000 5.

Security Considerations In order to implement this MIB, a probe must capture all packets on the locally-attached network, including packets between third parties. These packets are analyzed to collect network addresses, protocol usage information, and conversation statistics. Data of this nature may be considered sensitive in some environments. In such environments the administrator may wish to restrict SNMP access to the probe. This MIB also includes the ability to remove a station from a ring. Unauthorized use of this feature could constitute a denial of service attack. The administrator may wish to restrict access to the MIB object (ringStationConfigControlRemove) that implements this ability. There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write and/or read- create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB. It is recommended that the implementors consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2574 [12] and the View-based Access Control Model RFC 2575 [15] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
